step F, controlling the stepping motor 55 to run in reverse until the movable tray 2 is reset to the initial position;
and G, repeating the steps A-F.
When the device is used, the electric trolley is firstly driven to be close to an electrolytic aluminum groove of an electrolyte production workshop, then fluid electrolyte is scooped up by an operator and poured into the open space 15 of the sample box 1, then the sample box 1 is rapidly transferred to the position under the pressing mold handle 31 by the material transferring mechanism, then the pressing mold handle 31 is controlled to be pressed downwards by the material pressing cylinder 33 or the material pressing device until an electrolyte standard sample is pressed, then the sample box 1 with the electrolyte standard sample is transferred to be close to the material taking mechanism, and finally the material is taken by the material taking mechanism. And then, the electric trolley is driven to be close to the next electrolytic aluminum tank, and the processes are repeated until the preparation of the standard samples corresponding to all the equipment in the workshop is finished.
In the process of pressing the electrolyte standard sample, the end face of the pressing die handle is contacted with the top end of the standard sample ring, and after the electrolyte standard sample is pressed, the top surface of the electrolyte standard sample is flush with the top end of the standard sample ring. In the practical application process, the electrolyte standard sample and the standard sample ring can be integrally called as the electrolyte standard sample so as to be convenient for inspection.
The electrolyte standard sample prepared by the scheme of the invention can be directly pressed into the electrolyte standard sample by virtue of the electrolyte standard sample box, so that the problem of dust pollution is fundamentally solved, the poured electrolyte can be pressed into a compact electrolyte standard sample under the condition of preventing the poured electrolyte from overflowing, the compact and full electrolyte standard sample can be ensured as long as the open space is not filled with the poured electrolyte, and the invention also has the advantages of few preparation procedures of the electrolyte standard sample, convenience and simplicity in operation and the like.
The invention solves the technical problems of high cost, complex standard sample preparation process, low standard sample preparation efficiency and the like of the traditional electrolyte standard sample preparation by an extremely simple and ingenious technical route and device, particularly greatly improves the efficiency of preparing the electrolyte standard sample on the basis of saving two key processes of grinding into powder and pressing the powder into sheets in the traditional technical route, reduces the difficulty of preparing the electrolyte standard sample, and can smoothly complete the standard sample preparation work by any ordinary operator; the device provided by the invention also has the advantage of good flexibility, can realize the preparation at will (the material is taken at any time and the standard sample is prepared at once) under the condition of not occupying the fixed space of a production workshop, and is generally used for all relevant production workshops. Compared with the method for preparing the electrolyte standard sample by adopting the planetary ball mill, the method can further save labor force (taking 150 electrolytic aluminum tanks as an example, five operators are needed based on the traditional scheme of the prior document CN 103551225B), can prepare hundreds of electrolyte standard samples by only one operator every day, completely avoids the generation of dust, and is beneficial to environmental protection.
